Two porous containers are filled with Hydrogen and Neon respectively. Under identical conditions, 2/3 of the Hydrogen escapes in 6 hours. How long will it take for half the neon to escape?.
I really don't understand so, could anyone please explain in detail. Thank you. )-:.

initially, the lighter a particle is, the swifter it is going to pass. so in case you prefer some thing a million/2 as rapid, it is going to could desire to be heavier. in case you prefer some thing two times as rapid, it is going to could desire to be lighter. next is the proportion element. The equation has a sq. root radical in it, which you may properly be a million/2 as rapid, it ought to have 4x the mass, and to be two times as rapid it ought to have ¼ the mass. on condition that Ne has a mass of roughly 20, % the noble gas with a mass approximately 80, this is Kr examine: Vkr / Vne = sqrt(Mne / Mkr) = sqrt(20.18 / 80 3.8) = 0.491 Vkr = .491 x Vne. on condition that pentane (p) has a mass of roughly seventy two % the gas with the mass mass approximately seventy two/4 = 18. H2O is closest. examine: Vw / vice chairman = sqrt(Mp / Mw) = sqrt(seventy two/18) = sqrt(4) = 2 Vw = 2 x vice chairman
